Worked on enhancing the reliability of timeout handling tests in the gofiber/fiber repository, focusing on backend development and testing using Go. Addressed race conditions and improved the accuracy of timeout-related assertions to stabilize the test suite, particularly in scenarios involving context propagation. Refactored timer usage by adopting time.NewTimer to prevent resource leaks, ensuring more robust and maintainable tests. Applied gofumpt formatting to improve code readability and consistency across the timeout test codebase. These efforts reduced flaky test outcomes and improved continuous integration stability, contributing to more reliable validation of timeout semantics in the core library without introducing new features.
